| Abstract: | To increase the accuracy of gradient interpolation, the superconvergence principle and the method of elimination of unknowns are used, by which the accuracy of strees calculation can be increased by one order. In addition, the method to improve the accuracy of stress calculation for boundary points is also proposed. Calculations show that these methods are efficient. |
